ABSTRACT

Single-piece hinged-clamps employed used in assemblies used to mount solar power modules to surface installation are disclosed. In some embodiments, a clamp with a right portion with a right notch having a right platform, a left portion with a left notch having a left platform, and a base portion with a flexible hinge is disclosed. The left portion also includes a threaded aperture extending downwardly from the left platform. In some embodiments, a method of securing a component with the clamp is disclosed in which a right member of a component is inserted into a right notch of a clamp, an applied force imparts movement of a left notch away from the right notch, and a buildup of potential energy in the flexible hinge during the application of the force moves the left notch in the opposite direction to engage the left member of the component.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/988,677, filed Mar. 12, 2020, which is incorporated by reference herein in its entirety.

BACKGROUND

Building-mounted structures are typically secured to a building surface with one or more mounting assemblies. Such assemblies may include multiple components which coupled together to facilitate, for example, the ability to raise and lower track assemblies above an installation surface to which solar panel modules may be mounted during the installation of systems designed to generate solar power. One of these components could be a clamp which couples together two members of the mounting assembly in an arrangement desired for the installation. While clamps provide necessary functions to the installation process, each could be comprised of at least four separate components which an installer needs to handle simultaneously during the installation process: a threaded fastener, a nut, and two opposing members for providing a clamping force imparted by the tightening force applied to threaded fastener traversing through apertures of the opposing members to engage the nut with the proper amount of torque. During the installation of a solar power generation system, a significant delay can buildup due to the number of parts being fitted together.

SUMMARY

Embodiments of the inventive concepts disclosed herein are directed to a clamp assembly comprising a hinged-clamp, a fastener, and a spring. The use of this clamp assembly may improve installation time by reducing the number of parts with which the installer needs to handle and providing the installer a snapping feature to provide him/her an affirmative indication of that two structural members have been clamped together.

In one aspect, embodiments of the inventive concepts disclosed herein are directed to single-piece hinged-clamp. The hinged-clamp could include a base with a flexible hinge, a right sidewall with an aperture, a tapered right flange, a right platform, and a right notch formed by the tapered right flange and the right platform; a left sidewall extending from the flexible hinge and having a tapered left flange, a left platform, and a left notch formed by the tapered left flange and the left platform, where the left notch and right notch are collinear with each other; and a vertical member with a threaded aperture that extends between the left platform and the horizontal member.

In a further aspect, the single-piece hinged-clamp may be defined with a right portion with an aperture and a right notch having a right platform; a left portion with a left notch having a left platform collinear with the right platform, a horizontal member, and a threaded aperture in a vertical member extending between the left platform and the horizontal member; and a base portion extending between the right and left portions and comprised of a flexible hinge.

In a further aspect, embodiments of the inventive concepts disclosed herein are directed to a method for securing a component with the single-piece hinged-clamp.

FIGS. 1B-1C illustrate top and bottom perspective views of track assembly 100; FIGS. 1D-1E illustrate perspective views of hinged-clamp 110; FIG. 1F illustrates a cross-sectional side view of hinged-clamp 110; 1F illustrates a cross-sectional side view of hinged-clamp 110 with a release tab; FIG. 1F illustrate a side view of hinged-clamp 110; and 1I illustrates a side view of hinged-clamp 110 with a release tab.

Track assembly 100 includes a clamp assembly comprised of hinged-clamp 110 and fastening hardware 150 of fastener 152. In some embodiments, spring 154 could be employed. For the purpose of illustration and not of limitation, track 180 with right and left flanges 184 and 182, respectively, could be coupled to mount 190 configured to facilitate height-adjustability of track 180 to which solar panel modules may be coupled in a solar power generation system. Track 180 is disclosed in U.S. Design Patent No. D853,954; mount 190 is disclosed in detail in a patent application filed concurrently with this application that subsequently issued as U.S. Pat. No. 11,152,889, a reference which is incorporated herein in its entirety.

Hinged-clamp 110 includes base (or base portion) 112, right sidewall 114, left sidewall 116, and hinge 117 providing a curved or smooth transition from base 112 to left sidewall 116 which facilitates the insertion and removal of left and right flanges 184 and 182 of track 180 into right notch 118 and left notch 120, respectively, as track 180 is attached to and removed from clamp 110, respectively. In some embodiments, the curved or smooth transition facilitates flexibility with a downward swing and a simultaneous buildup of potential energy in hinge 117 during the clamping process as discussed below. A right portion of hinged-clamp 100 could include distal end 122 of right sidewall 114 includes right flange 124 tapering angularly downward and inwardly towards left sidewall 116. Also, the right portion could include right platform 126 extends inwardly and approximately perpendicularly away from inner surface 128 of right sidewall 114; together with tapered right flange 124, right platform 126 forms right notch 118. Right sidewall 114 includes aperture 130 through which fastener 152 extends when clamp 110 is coupled to mount 190.

A left portion of hinged-clamp 100 could include distal end 132 of left sidewall 116 includes left flange 134 tapering angularly downward and inwardly towards right sidewall 514. Also, the left portion could include stop structure 136 includes left platform 138, horizontal member 140, and vertical member 142 extending between left platform 138 and horizontal member 140; together with tapered left flange 134, left platform 138 forms left notch 120. Vertical member 142 includes threaded aperture 144 for receiving fastener 152 when clamp 110 is coupled to mount 190. Opposing vertical stops 146 extend towards each other from left platform 138 and horizontal member 140, providing a gap or space between stops 146.

In some embodiments, stops 146 may provide a visually indication of a prescribed depth insertion of fastener 152 during a two-step process for attaching track 180 to mount 190. In a first step, mount 190 could be coupled to hinged-clamp 100 by inserting fastener 152 through aperture 130 and threadably engaging it with threaded aperture 144 in a tightening process until the tip of fastener 152 reaches stops 146 to provide a visual indication that fastener 152 has reached the prescribed depth insertion. At this point, hinged-clamp 100 is not fastened to mount 190 because the head of fastener 152 does not exert a compressive force against its mating vertical surface of mount 190. At this point, hinge 117 is capable of swinging downwardly.

In the second step, track 180 may be attached to hinged-clamp 100 as described below. Then, the tightening process continues until the head of fastener 152 exerts a compressive force upon its mating vertical surface of mount 190 until the prescribed, final torque has been reached. During this tightening process, the threads of the tip of fastener 152 could be forced between stops 146, especially in instances where fastener 152 is materially harder (e.g., steel) than stops 146 (e.g., aluminum). At this point, track 180 has become attached to mount 190 through hinged-clamp 100, and hinge 117 is no longer capable of swinging downward.

In some embodiments, track 180 could be attached to hinged-clamp 100 by inserting right flange 184 into right notch 118, pressing the tip of left flange 182 against left flange 184, and applying a downward force to track 180 as it is continually pressed against left flange 184, thereby imparting a downward travel to left flange 182, a horizontal or outward travel of left notch 120, and a downward swing of hinge 117 until left flange 182 reaches left notch 120, whereupon left notch 120 decisively snaps into its place around left flange 182 for a notchable engagement. The snapping action results from a release of potential energy built up in hinge 117 during the application of the force.

In some embodiments, track 180 could be attached to hinged-clamp 100 by inserting left flange 182 into left notch 120, pressing the tip of right flange 184 against right flange 184, and applying a downward force to track 180 as it is continually pressed against right flange 184, thereby imparting a horizontal or outward travel of left notch 120, a downward swing of hinge 117, and a compression of spring 154 until right flange 184 reaches right notch 118, whereupon right notch 118 decisively snaps into its place around right flange 184. The snapping action results from a release of potential energy built up in hinge 117 during the application of the force.

In some embodiments, the left portion of clamp 110 includes a release tab 160 comprising member 162 extending outwardly away from left sidewall 116; with member 162, an installer may press downward on it with his/her hand to impart a horizontal or outward travel of left notch 120, a downward swing of hinge 117, and a compression of spring 154. In some embodiments, a release tab 160 could include member 164 extending upwardly away from distal end 166 of member 162 to facilitate the use of release tool 170. In some embodiments, member 164 extends angularly to form an acute angle 168 as shown.

FIGS. 1H-1I illustrate two side views of release tool 170 positioned in release tab 560 and applied to the track as shown to enable the release of left flange 182 of clamp 110 from clamp 110 as shown. In some embodiments, release tool 170 could be any solid object such as, but not limited to, a screwdriver and socket wrench placed in release tab 160 and against track 180. To release track 180 from clamp 110, a force is applied to track 180 through release tool 170, imparting a downward swing of hinge 117, a compression of spring 154, and a horizontal or outward travel of left notch 120 until left flange 182 clears left notch 120. In some embodiments, release tool 170 may not be necessary; rather, a person could apply a downward force against release tab 560, imparting a downward swing of hinge 117, a compression of spring 154, and a horizontal or outward travel of left notch 120 until left flange 182 clears left notch 120.

It should be understood that the aspects, features and advantages made apparent from the foregoing are efficiently attained and, since certain changes may be made in the disclosed inventive embodiments without departing from the spirit and scope of the invention, it is intended that all matter contained herein shall be interpreted as illustrative and not in a limiting sense.
